1, moisture-proof: starch is easy to absorb moisture, swell and even rot and mildew. Therefore, it must be kept dry during storage to prevent moisture. If you encounter high temperature under high humidity, starch may gelatinize. Therefore, the general indoor temperature should be kept below 65438 05℃, the relative humidity should not exceed 70%, and attention should be paid to ventilation.

2, to prevent odor: because of the strong water absorption of starch, while absorbing water, the performance of absorbing odor is also very strong. Therefore, when storing, it should be prevented from being stored with articles with peculiar smell. If it is contaminated by odor, it can be dried to reduce or eliminate odor.

3, prevent insect bites: starch, like all kinds of food, is easy to cause insect bites or mouse bites. Therefore, in addition to keeping the warehouse clean during preservation, it is also necessary to do a good job of pest control and rodent control.
